F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER
The F90 is equipped with two standard light-emitting diodes
(LEDs) and one optional LED.
This sizing information in the following Examples 1, 2, and 3
was generated using the ASHRAE Handbook of
Fundamentals, 1990 and the ASHRAE Standard 62-1989,
Ventilation for Acceptable Indoor Quality. These examples
simplify the sizing procedure for most applications. Use this
information as a guide; however, keep in mind that the F90
has different capacities for each fan speed (see
Specifications section).
ON LED: Lights when the solid state power supply is
powered and operating normally.
CHECK LED: Lights if the F90 requires service or if the
test button is pressed.
WASH LED (if used): Lights when cell washing is overdue.
To understand the operating sequence of the F90, refer to
Fig. 3.
The number of air changes per hour determines the number
of F90s needed. More air changes per hour than indicated
are unnecessary because the ASHRAE data from which
these examples were constructed is conservative. Fewer air
changes per hour can be compensated for by bringing in
more outdoor air to maintain low contaminant levels or
tolerating a partially cleaned atmosphere. Either may be
acceptable to some users.
Determine Number of F90 Needed
The sizing procedure determines the number of F90s needed
for any application. The correct number required for a
particular application depends on:
—

—
—
—
type of contamination.
number of occupants.
volume of the room.
use of the room.
Regardless of the method used for calculation, the
architectural features, lighting fixtures, sprinkler system,
ducts, and grilles in the room to be cleaned may influence the
number of F90s required. For ambient air cleaning, establish
a uniform airflow pattern throughout the entire space. When
there is a lack of mounting space, fewer F90s than indicated
may be installed. More F90s may be required for oddly-
shaped rooms that do not have even airflow.

Mount the F90 on the ceiling near the center of the room. A
45° diagonal mounting prevents stale air build-up in corners
and may allow use of F90s at lower speeds. See Fig. 4. In
larger rooms, divide the area into sections and mount an F90
in the center of each section. In rooms requiring varying
levels of air cleaning, concentrate F90s where air cleaning is
required most. See Fig. 4.

NOTE: To assure even air distribution, the F90 draws air
into the bottom of the air cleaner and discharges air
in four directions as shown in Fig. 5. This Coanda
air flow pattern assures that the clean air is
distributed to all parts of the space. Also, if possible,
mount the F90 to aid the air circulation already
established in the room.

Example 1. Sizing by Air Changes per Hour and Room Volume
An office measures 40 x 45 feet (12 x 14 meters) with a 15 foot (4.5 meter) ceiling. How many F90As should be installed?
Solution:
1. Find the room volume: 40 x 45 x 15 feet = 27,000 cubic feet, (12 x 14 x 4.5 meters = 756 cubic meters).
2. Assuming seven air changes per hour, with 27,000 cubic feet (756 cubic meters) volume, the graph below indicates three
F90As are required.
3. Clean outdoor air is also required to replenish oxygen and dilute gaseous contaminants. 20 cfm per person is required for
offices.

Example 2. Sizing by Occupant Load
A cocktail lounge averages 85 occupants. How many F90As should be installed?
Solution:
F90As Required = ASHRAE Recommended Air Circulation/Minute
F90A Capacity
3
1. ASHRAE recommended minimum air circulation is 30 cubic feet per minute (cfm) (0.85 m /minute) per person. For 85
3
3
people, the recommended air circulation would be: 85 people x 30 cfm (0.85 m /minute) per person = 2550 cfm (72 m
minute).
3
2. F90A capacity (HI setting) is 1250 cfm (35 m /minute).
3
Number of F90A's Required = 2550 cfm = 2 F90A's 72 m /minute = 2 F90As
1250 cfm
35 m3/minute
3. Clean outdoor air is also required to replenish oxygen and dilute gaseous contaminants. 30 cfm per person is required for
bars and cocktail lounges.
EXAMPLE 3. Sizing by Air Changes per Hour and Room Volume
A shop proprietor wants to use F90As to remove high levels of smoke from the air. The shop is 25 x 40 feet (8 x 12 meters) with
a 15 feet (4.5 meters) ceiling. How many F90As are required?
Guideline: In the absence of other information, select the correct number of F90A units to provide between 10 and 20 air
changes per hour, depending on contaminant level. The F90As should be located directly above or as close as
possible to the source of contamination.
Solution:
F90As required = Desired Air Circulation/Minute
F90A Capacity
1. Calculate the volume of the room: 25 x 40 x 15 feet = 15,000 cubic feet, (8 x 12 x 4.5 meters = 432 cubic meters).
2. Determine the volume of air to be circulated each hour. Ten air changes per hour are used here on the assumption that
the intent is to reduce, but not completely eliminate, smoke. 15,000 cubic feet x 10 air changes/hour = 150,000 cubic
feet/hour (432 cubic meters x 10 air changes/hour = 4320 cubic meters/hour)
3. Determine the volume of air to be circulated each minute:
3
150,000 cubic feet/hour = 2500 cubic feet/minute (cfm) 4320 cubic feet/hour = 72 cubic meters/minute (m /minute)
60 minutes/hour
60 minutes/hour
3
4. F90A capacity (HI setting is 1250 cfm (35 m /minute).

Wall Mounting Kit (Accessory)
Mounting the F90A Using the
272577A Transition Plate
(Accessory)
Two wall mounting brackets are used to support the F90. See
Fig. 11. The two brackets must be mounted on the wall with
16 in. (406 mm) for the F90A or 8 in. (203 mm) for the F90B
between centers so that the lag bolts will align with the F90
mounting holes. Fasten the brackets to the wall studs with
lag screws. On masonry walls, use appropriate screw
anchors.
The transition plate (Fig. 10) allows the F90 to be mounted
by one person. In the two-step process, the mounting plate is
first secured directly to the ceiling joists. Then the F90 is
mounted to the transition plate.
Eight flanged locknuts (four large, four small) and four 3/8 by
3 in. (10 by 76 mm) lag screws are provided with the
transition plate. The four large locknuts adjust the F90 height,
level the F90, and provide stops for the F90 top plate (when
tightened). The four smaller locknuts secure the F90 to the
ceiling joists.
Wiring
IMPORTANT
All wiring must comply with local codes and
ordinances.
1. Screw a large height-adjusting nut on each stud.
Assure that the large nut is screwed on with its flanged
portion down.
2. Position and level the height adjusting nuts so flanges
are flush with the lag screw heads or the protruding
threaded steel rods.
3. Screw a small securing nut on each stud, leaving a 1/2
in. (13 mm) space between it and the height adjusting
nut.
4. Lift the F90 into position and locate the four studs.
5. Raise the F90 so that the four studs pass through the
keyhole openings.
Power Cord
IMPORTANT
Power supply cord must not be concealed above
the ceiling or behind the walls.
The F90, 120 Vac has a standard 3-prong plug on a 10 foot
(3 meter) power cord. There must be a standard grounded
outlet within 10 feet (3 meters) of the F90. The F90, 220/240
Vac power cord terminates in stripped leadwires for
installation of a locally purchased plug.
6. Slide the F90 horizontally so the studs are located at
the slot end of each keyhole opening.
•
•
Do not use an extension cord to power the F90.
Keep the power cord out of the reach of building
occupants.
NOTE: As viewed from the F90 or floor side, the slot
portion of each keyhole is above the surface
of the top plate. Position the F90 so the studs
are located at the slot end of each keyhole.
When the securing nuts are tightened, they
should nest firmly in the sockets to prevent
any lateral movement.
•
•
Keep the power cord away from water.
Do not route the power cord near sharp objects that can
damage the cord insulation.

Cleaning the F90
Cleaning the Cell Using Alkaline
Base Detergent
The F90 removes a variety of contaminants from the air. As it
cleans the air, the F90 cells and prefilters become dirty,
lowering the cleaning efficiency. To maintain the F90
reliability and efficiency, regularly clean, inspect, and service
the F90 cells and prefilters.
WARNING
Hazardous Chemical.
Can cause personal injury.
Wear rubber gloves, eye protection, and a rubber
apron for protection from the strong cleaning
chemicals. Keep detergent solution out of reach
of children.
Clean cells with an alkaline base detergent solution. Soaking
the cells in commercial or home electric dishwasher
detergent, powder or liquid, works well. Use the hottest water
possible (hotter than 160°F (71°C)). If soaking does not clean
the cells, use high velocity detergent spray or steam. Full
service distributors provide a regular cleaning service to
commercial establishments.
1. Use a container such as a laundry tub or plastic tank
that is large enough to hold at least one cell.
2. Mix the alkaline base detergent with hot water, carefully
following the instructions on the detergent package.
The WASH LED (if used) lights when cell washing is
overdue. When the WASH LED lights, wash the cells and
wipe the ionizer wires. Frequent cell cleaning keeps WASH
LED
•
Use commercial or home electric dishwasher
detergent (either powder or liquid). Do not use
soap or acid base cleaners or solvents.
Assure the water temperature is between 150°F
and 190°F (66°C and 88°C).
If using cold water detergent, follow the
instructions included with the detergent.

2. When servicing the F90, stand on a stable
work platform or ladder.
1. Open the cover by pulling the two latches located on
the front of the cover and swinging the cover down until
it hangs. See Fig. 13.
2. Remove the prefilter and the cell from the channel
guides.
3. Replace the activated carbon filter (if used), if it
needs replacement.
Cleaning the Prefilter
1. Shake out or vacuum the accumulated contaminants
from the prefilter. If necessary, soak the prefilter in
alkaline detergent solution. Do not soak the prefilter in
an acid detergent solution or use high pressure water,
air, or steam to clean the prefilter.
M922A
Fig. 14. When cleaning cell, agitate in detergent solution.
3. Carefully wipe off ionizer wires before prerinsing.
4. Prerinse the cell in hot water before submerging
in detergent.
5. Soak the cell in the solution for up to 15 minutes.
Agitate the cell in the solution if necessary. See Fig.
14.
NOTE: Wash the cell before washing the prefilter. If the
prefilter is washed first, lint residue from the prefilter
will contaminate the wash water and deposit inside
the cell. Dispose of the wash water after each use.
6. Remove the cell from the detergent solution.
7. Place the cell in another container of clear hot water
(150°F to 190°F (66°C to 88°C)) for final rinsing. Rinse
the cells for five to ten minutes.
8. Remove the cell from the rinse water. Allow the cell to
drain and dry before energizing. Stand cell on one
corner for optimum water drainage.

Modifying to Reduce Ozone Odor
A person with an average sense of smell can detect the odor
of ozone indoors in concentrations as low as 0.003 part per
million (ppm). OSHA workplace regulations permit up to
0.100 ppm ozone concentration. The F90 contributes 0.005
to 0.010 ppm of ozone to the indoor air. The U.S. FDA and
Health and Welfare Canada recommend that indoor ozone
concentration should not exceed 0.050 ppm. As a
comparison, the outdoor ozone level in major cities is
sometimes higher than 0.100 ppm.
In normal operation, the F90 generates a trace amount of
ozone that is considerably under the limit prescribed by the
U.S. Food and Drug Administration (FDA). During the first
week or two of operation, the amount may be higher because
of sharp edges on some of the new high voltage metal parts.
Normal use dulls these edges in a short time.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER
If desired, the ozone generated by the F90 can be reduced
in one of two ways:
•
•
Install the optional activated carbon filters.
Open the cover and move the F90 performance switch to
the LO setting. Close the cover. With the switch in LO, the
cleaning efficiency is reduced 5 to 15 percent, depending
on airflow.
Tools And Equipment
Troubleshooting the F90 requires:
•
Needlenose pliers for stringing ionizer wires and inserting
edge connectors.
•
Test meter with 15 kVdc probe.
NOTE: The performance switch must be set solidly in either
HI or LO position and not between, or the F90 may
not function properly. See Fig. 19.
